Maybe he'd like to get to know you better, but he's shy and unsure what to say in an actual message. Or, he might be the kind of guy who winks at a lot of woman and can't be bothered sending a message. If this is the case, it doesn't mean much.
The law of conservation of mass (from Lavoisier) states that mass can be neither created nor destroyed (but it may change its form into something that is not desired, such as heat with an engine) or that in a chemical reaction, the total mass of the reacting substances is equal to the total mass of products formed.
The law of conservation of mass states that mass cannot be created nor destroyed. However, in modern physics, this is not true. It has been observed that energy can be convert â¦ ed to mass and mass to energy. So, now, the law has been changed to mass-energy cannot be created nor destroyed in modern physics. In chemistry,however, the former is true.
